Bill after solar power installation

Postby Dazzacarter » Mon Aug 15, 2016 8:11 pm

Hi everyone
We installed a 5.5 kW system about 3yrs ago and was told it wold pretty much pay for itself with the savings we would get. We use the power for cooking etc during the day and we got rid of our hot water tariff and still r getting $400 Bills, just not sure if this is still to much or am I expecting to much
Regards frustrated

Welcome to the Energy Matters Forums Dazzacarter :)

More information would be required before any indication could be given about what is going on with your solar power and bills.

Are your bills unchanged since before you had solar power?
How many units per day were you using then, and how many now?
What is the distribution of your power usage - is much of your output used during the day when most power is being produced by your system, or do you use most at night?
How many kWh per day is your system producing?
Is any of your solar array shaded at all during the day, by TV antennae, trees etc?
How much are you being paid per unit of exported electricity?
Have the fixed charges or the charge per kWh imported changed since before you had your system installed?
Do you have any sort of solar system/energy monitoring/logging? Loomberah weather and astronomy including live solar radiation intensity and UV + Gunagulla aquaponics, organic eggs and cherries

I have a much smaller system and did not expect it to fully support us. But if i had a 5.5 Kw system I would have high expectations even allowing for the very low price paid back for power now.
However the details are important as the others have already said. How many in the family, ages, where are you, what are the details of the contract, meter type etc etc.

My bill sets out the three levels of charging rates and I could go back and compare. However yor supplier may be able to explain what system he(she) has set up for you and how that may be changed for your advantage.
